Intercept: 4

Minimum value:

#### Explanation:

From the equation, any number behind

Next, complete the square so that the equation is in the form of

If you don't know how to complete a square, it's like this:

- Divide the coefficient of
#x# by#2# - Take the square out of the
#x# , so you will get#(x-2)^2# - Then square the
#2# inside the bracket, which gets you#(x-2)^2-4+4# - Finally simplify the equation.
#(x-2)^2#

Since there is no number after the brackets, the minimum value of

Minimum points=

(Always switch the negative signs into positive and vice versa for the completed square!)
